Beschreibung
Zusammenfassung:	The present invention provides a print product which has a printed region where printing with ultraviolet laser is applied and which is excellent in viewability, a method for producing a print product by irradiation with ultraviolet laser, and a printing medium for laser printing, for use in the print product and the method for producing a print product. The print product of the present invention has a printed region comprising discolored titanium oxide in at least one portion of a sheet medium selected from the group consisting of paper or a film having a printable region comprising titanium oxide; titanium oxide is filled in the sheet medium; a titanium oxide content in the printable region in the sheet medium is 1.0% by mass or more, pulp constituting the paper has a length weighted average fiber length and an average fiber width in specified ranges, and the paper has a basis weight of 20 g/m 2 or more, when the sheet medium is the paper; a titanium oxide content in the printable region in the sheet medium is 0.3% by mass or more, the film has a thickness of 15 pim or more, and a resin constituting the film comprises a specified resin, when the sheet medium is the film; and a ratio between a Raman intensity assigned to titanium oxide in the printed region and a Raman intensity assigned to titanium oxide in a non-printed region is 0.70 or less.
